Uses of Scope in io.opentracing

Methods in io.opentracing that return Scope

Modifier and Type	Method and Description
Scope	ScopeManager.activate(Span span) Set the specified Span as the active instance for the current context (usually a thread).
Scope	ScopeManager.activate(Span span, boolean finishSpanOnClose) Deprecated. use ScopeManager.activate(Span) instead. Set the specified Span as the active instance for the current context (usually a thread). Finishing the Span upon close() is discouraged, as reporting errors becomes impossible: try (Scope scope = tracer.scopeManager().activate(span, true)) { } catch (Exception e) { // Not possible to report errors, as // the span has been already finished. }
Scope	Tracer.activateSpan(Span span) Make a Span instance active for the current context (usually a thread).
Scope	ScopeManager.active() Deprecated. use ScopeManager.activeSpan() instead. Return the currently active Scope which can be used to deactivate the currently active Span. Observe that Scope is expected to be used only in the same thread where it was created, and thus should not be passed across threads. Because both ScopeManager.active() and ScopeManager.activeSpan() reference the current active state, they both will be either null or non-null.
Scope	Tracer.SpanBuilder.startActive(boolean finishSpanOnClose) Deprecated. use Tracer.SpanBuilder.start() and ScopeManager.activate(Span span) instead. Returns a newly started and activated Scope. SpanBuilder#startActive() is a shorthand for tracer.scopeManager().activate(spanBuilder.start()). The returned Scope supports try-with-resources, but using this method is discouraged as the Span reference could be easily lost, and reporting errors on Span through this method becomes impossible: try (Scope scope = tracer.buildSpan("...").startActive(true)) { // (Do work) scope.span().setTag( ... ); // etc, etc } catch (Exception e) { // Not possible to report errors, as // the span reference has been lost, // and span has been already finished too. } It is recommended to use Tracer.SpanBuilder.start() with a subsequent call to ScopeManager.activate(Span) Span span = tracer.buildSpan("...").start(); try (Scope scope = tracer.activateSpan(span)) { } catch (Exception e) { span.log(...); // Report any errors properly. } finally { span.finish(); // Optionally close the Span. }
